In addition, all front cameras at present cannot realize a zooming function.
The application provides a display device, a preparation method thereof and electronic equipment, and aims to solve the technical problem that a display screen occupies a relatively low area in the prior art.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments.
The embodiment of the application provides a display device, as shown in fig. 1-2, mainly comprising a display panel 10, a light condensing module 30 and a light sensing module 40. The display panel 10 is provided with a light-passing structure 20; the light condensing module 30 is disposed at one side of the display panel 10, and is used for condensing the light incident from the outside, so that the condensed light passes through the light passing structure 20; the light sensing module 40 is disposed at a side of the display panel 10 away from the light condensing module 30, the light sensing module 40 includes a light sensing structure 41, and the light sensing structure 41 corresponds to the light passing structure 20 and the light condensing module 30, and is used for obtaining scattered light after passing through the light passing structure 20; the projection area of the light transmitting structure 20 at the photosensitive module 40 is smaller than the area of the photosensitive structure 41.
Alternatively, the display panel 10 may be an LCD display panel, an OLED display panel, a miniLED display panel, or a micro led display panel.
Optionally, the display panel 10 includes a first area and a second area, where the first area is a display area, and the second area is configured to be light-transmitting, so that the light-transmitting structure 20 is disposed, and the arrangement of the light-transmitting structure 20 does not affect the normal display of the display panel 10. The light condensing module 30 is disposed on the display side of the display panel 10, that is, the light emitting side of the display panel 10, and is configured to condense light on a side far away from the display panel 10, and make the condensed light pass through the light passing structure 20, where an intersection point of the condensed light may be located in the light passing structure 20. The photosensitive module 40 at least comprises a camera and a photosensitive structure 41, wherein the photosensitive structure 41 is positioned in the display device and arranged below the display panel 10 to obtain light scattered after passing through the light passing structure 20, so as to form clear imaging.
In this embodiment, by using the principle of pinhole imaging (light propagates along a straight line in the same homogeneous medium without being interfered by the action of gravity), the light-condensing module 30 on one side of the display panel 10 changes the light path to form convergence, and makes the converged light pass through the light-passing structure 20 to increase the light transmission amount, so as to ensure that the photosensitive module 40 can receive enough light to obtain high-quality imaging, and this embodiment has simple structure, high feasibility, no need of other hardware cooperation and low cost; the projection area of the light passing structure 20 at the photosensitive module 40 is smaller than the area of the photosensitive structure 41, so that the screen occupation ratio can be improved, and the requirement of full-screen display can be further met.
Alternatively, as shown in fig. 2, the light condensing module 30 includes a first layer structure 31, and a light condensing structure disposed on a side of the first layer structure 31 away from the display panel 10; the light condensing structure comprises a curved surface 32, the curved surface 32 is positioned on one side of the light condensing structure far away from the display panel 10, and the curved surface 32 protrudes out of the light condensing structure.
The first layer structure 31 may be a touch panel, and a light condensing structure is disposed in a partial area on the touch panel, and the light condensing structure may be a liquid crystal prism composed of liquid crystal molecules, and the liquid crystal prism has a curved surface 32 protruding from the touch panel, where the curved surface 32 is located on a side of the light condensing structure away from the display panel 10, forming a convex lens structure, and light entering the curved surface 32 from the outside changes a light path through the convex lens, so that the light is condensed, and passes through the light transmitting structure 20 to ensure that a sufficient light transmission amount passes through the display panel 10.
Optionally, as shown in fig. 2, the photosensitive module 40 further includes a second layer structure 32; the photosensitive structure 41 is disposed on a side of the second layer structure 32 facing the display panel 10.
The second layer structure 32 may be a mounting structure within a display device. For example, when the display panel 10 is an LCD display, the second layer structure 32 is a backlight module, which includes a bottom frame, a light shielding adhesive, a light enhancement film, a diffusion film, a reflective film, a light guide plate, and a light source. The camera of the photosensitive module 40 may be disposed on the backlight module, or may be disposed between the photosensitive module 40 and the display panel 10.
An optical sensor may be disposed on the second layer structure 32, and a photosensitive structure 41 is disposed on the optical sensor, where the photosensitive structure 41 is disposed on a side of the second layer structure 32 facing the display panel 10, so as to receive the light scattered after passing through the light passing structure 20.
Alternatively, as shown in fig. 1-2, the light condensing structure includes a liquid crystal cell 33; the display device further comprises a control module electrically connected with the liquid crystal unit 33, wherein the control module is used for changing the long axis and/or the short axis of the liquid crystal unit 33 by adjusting the voltage of the liquid crystal unit 33 so as to adjust the focal length of the liquid crystal unit 33.
A liquid crystal cell 33 is disposed on a side of the first layer structure 31 remote from the display panel 10, the liquid crystal cell 33 is of a convex lens structure, and a convex surface of the liquid crystal cell 33 is the curved surface 32 and protrudes from the first layer structure 31. After the control module obtains the instruction, the control module controls the form of the liquid crystal unit 33, that is, the shape of the convex lens structure is changed by changing the voltage applied to the liquid crystal unit 33, so as to control the change of curvature and focal length. Wherein the larger the curvature, the smaller the focal length; the liquid crystal cell 33 has a curvature within an adjustable maximum curvature range regardless of the shape of its lenticular structure. The adjustable maximum curvature refers to the maximum curvature that the convex lens structure has, and the focal length of the convex lens structure at the maximum curvature is the smallest. Because the focal length of the convex lens structure formed by the liquid crystal unit 33 is adjustable, shooting with different depth of field can be realized, and shooting imaging quality is further improved.
Optionally, as shown in fig. 2, the light passing structure 20 includes a through hole.
The through holes are disposed along the thickness of the display panel 10, and the through holes may have a circular, rectangular, trapezoidal or oval cross-sectional shape in the longitudinal or transverse direction. The size of the optical sensor is hundreds of nanometers, and the aperture size of the through hole is one tenth of that of the pixel unit of the optical sensor, namely, the aperture size of the through hole is tens of nanometers; the aperture size of the through holes is also affected by factors such as the pixel resolution of the display panel 10, the size of the pixel pitch, the thickness of the display panel 10, and the like. Specifically, the smaller the resolution of the display pixels, the larger the pixel pitch, and the larger the aperture of the through hole; the larger the thickness of the display screen is, the less light is received by the optical sensor under the same aperture of the through hole; the larger the aperture of the through hole, the more light the optical sensor receives.
Optionally, the light-transmitting structure 20 includes a light-transmitting layer disposed within the display panel 10.
The second area of the display panel 10 can be further provided with a light-transmitting layer, so that on the premise of ensuring normal display, shooting or shooting is performed through the light-transmitting layer, the shooting effect is not affected, and the requirement of full-screen display can be met.
Alternatively, as shown in fig. 3, the display panel 10 includes a sub-pixel region 11; the light passing structure 20 is disposed between any two sub-pixel regions 11.
The display panel 10 includes a plurality of sub-pixel regions 11, and the plurality of sub-pixel regions 11 may be arranged in a matrix or in any shape. The light emitted from the sub-pixel region 11 is one of the three primary colors of red (R), green (G), and blue (B), and thus the plurality of sub-pixel regions 11 can make the pixel emit light of various colors by the cooperation of the three primary colors. The light passing structure 20 can be arranged between any two adjacent sub-pixel regions 11, so that the space between any two adjacent sub-pixel regions 11 can be reasonably used, and the damage to the distribution in the sub-pixel regions 11 can be avoided, thereby reducing the display effect of the display panel 10.
Optionally, the number of the light condensing structures is plural, the number of the light passing structures 20 is plural, and the number of the photosensitive structures 41 is plural, and all are distributed in an array; the positions of one light condensing structure, one light passing structure 20, and one photosensitive structure 41 correspond, so that the light condensed by one light condensing structure is transmitted to the corresponding one photosensitive structure 41 through the corresponding one light passing structure 20.
The same number of light condensing structures, light transmitting structures 20 and light sensing structures 41 are distributed in an array and are in one-to-one correspondence, so that the arrangement can ensure that each light sensing structure 41 can acquire enough light to form high-quality imaging.
In addition, one light condensing structure can cover a plurality of light transmitting structures 20, so that the process difficulty can be reduced, the light incoming quantity can be increased or decreased, and the size of the light condensing structure can be set in the range from hundreds of nanometers to tens of micrometers.
Based on the same inventive concept, the embodiment of the present application provides an electronic device, including the display device provided in any one of the foregoing embodiments of the present application.
The electronic device in the implementation of the present application may be any device provided with the display screen in the foregoing embodiment, for example, a mobile communication terminal (for example, a mobile phone), a PDA (Personal Digital Assistant, a palm computer), a mobile computer, a tablet computer, a wearable device, and the like.

The manufacturing method of the display device in this embodiment corresponds to the structure of the display device in the foregoing implementation, so that a detailed description is omitted.
By applying the embodiment of the application, at least the following beneficial effects can be realized:
the light-gathering module 30 is positioned at one side of the display panel 10, and the converged light passes through the light-passing structure 20 of the display panel 10, so that the photosensitive module 40 positioned at one side of the display panel 10 far away from the light-gathering module 30 can receive enough light, thereby improving the lighting amount of the photosensitive module 40 and the shooting effect so as to obtain high-quality imaging; the projection area of the light passing structure 20 at the photosensitive module 40 is smaller than the area of the photosensitive structure 41, so that the screen occupation ratio can be improved, and the requirement of full-screen display can be further met. In addition, through the voltage regulation of the control module, the focal length of the light condensation module 30 is adjusted, so that shooting with different depth of field can be realized, and shooting imaging quality is further improved.
